It may be noted that the article is titled Kalpa Vedanga to distinguish it from Kalpa, the time terminology. [[File:Kalpa Sarwang.png|none|thumb|500x500px|'''Guru describing preparation of Vedi for Yajna''']]
== Introduction ==
The origin of Kalpa was for the organization of all the extensive rituals described in Vedas (वैदिककर्मकाण्डः | Vaidika Karmakanda). Kalpas are texts classified under the [[Shad Vedangas (षड्वेदाङ्गानि)|Shad Vedangas]]. They include the contents directly mentioned in Brahmanas and Aranyakas, presented in a systematic manner, explaining those not mentioned explicitly in the Brahmanas and omitting others not directly related to a particular yajna or ceremony.
The Kalpasutras are a veritable repository of ancient vedic traditions and amply augment and elucidate the cultural data derived from the Samhitas and Brahmanas. They are the "sutras" that interlink the Vedas and the modern day life.<ref name=":0" />

== Sutra Style of Writing ==
As we see the Vedas and their extensive associated literature needed to be preserved for the coming generations. In order to accomplish the task of preserving the precious mass of cultural traditions in a manageable and recollectable form, the seers of ancient Bharata invented the style of composition of texts characterized by utmost brevity and rigid systematization. A short sentence composed in this peculiar style is called Sutra, i.e., a thread. A diffuse and scattered precepts are succinctly systematized in a compact sentence called sutra, just as the loose fibres are compressed into a terse thread.
Among the different types of Sutras composed during Sutra period the Kalpasutras are by far the most important reflecting the cultural history of that period.<ref name=":0" />
Four classes of Kalpasutras ==
Kalpa Vedanga deals with four types of Sutragranthas, all closely allied and complementary to each other. They are
